IMPROVEMENT IN ADJUSTABLE HVDRANTS.

Specification forming part of Letters Patent No. 161,740, dated April 6,1875; application filed February 13, 1875.

To all whom it may concern:

Be it known that I, GEORGE D. BLOCHER, of Martinsburg, in the county ofBerkeley and State of West Virginia, have invented a new and valuableImprovement in Adjustable Hydrant; and I do hereby declare thatthefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingsmaking a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawing is a representation of a longitudinal verticalsection of my hydrant. Figs. 2, 3, and 4 are horizontal sectional viewsof the same; and Figs. 5 and 6 are detail views.

This invention relates to hydrants; and my object is to provide a\vaste-)assage for allowing water to escape from one side of the cock when theflow from the nozzle of the discharge-pipe is out off, thus preventingthe formation of ice in said pipe during the winter months.

In the annexed drawings A designates the case of the hydrant, on thebase or floor of which the body B of the cock is rigidly secured. Thisportion B is constructed with a tubular neck, a, to which theservice-pipe is suitably secured; and at right angles to this neck a awastepassage, 1), is made through the body B. O designates the tubularcockplug, having a hole, 0, through one side, which can be made toregister with the neck a, or with the passage 12, by turning the plug 0.D designates the discharge pipe, which rises from the plug 0, and passesthrough the top of the case A, and has a discharge-nozzle, d,

on its upper end. E designates a semicircular bridge, which keeps theplug 0 in its seat, and on which may be printed the words Winter andSummer, for the purpose of showing which way to turn the cock-plug whenit is desired to allow water to escape from pipe D through thewaste-passage b. Two holes, 0 e, are made through the bridge E, onopposite sides of the center thereof, through one or the other of whicha pin, f, is passed, against which the nozzle cl abuts when it is in aposition for drawing water, and the hole 0 in plug 0 registers with theneck a, as

shown in Figs. 1 and 4.

During the summer months, when the wastepassage is not brought intoplay, the checkpinfis inserted in to the hole 6; but when there isdanger of water freezing in the dischargepipe D the pin f is adjusted inthe hole 6, and the hole 0 in the cock-plug can be made to register withthe waste-passage for allowing water to escape from the discharge pipethrough said passage.

What I claim as new, and desire to secure by Letters Patent, is

In a hydrant having a waste-passage, b. a tubular plug, 0,discharge-pipe D, and nozzle 61, the bridge E, perforated at e e, andremovable pin f, all combined in the manner described. 1

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

GEO. D. BLOOHER.
